What would happen if Harry goes back in time to fourth year in fanfiction?

In fanfiction, if Harry goes back in time to the god, he might gain some extraordinary powers. Maybe the god would bestow upon him the ability to control magic in ways he never could before. It could also lead to him changing the course of history, for better or worse.

If Harry Potter goes back in time to teach fanfiction, it would be a really strange and interesting scenario. First of all, the wizarding world might not understand what fanfiction is at first. Harry would have to explain that it's a form of writing where fans create their own stories based on the original. He could inspire young witches and wizards to be more creative with the Harry Potter story itself. Maybe some of them would come up with really unique magical adventures that even J.K. Rowling hadn't thought of. Also, it could cause some chaos as the concept of fan - created stories might be a bit too modern for the old - time wizarding community.

She could change many important events. Maybe she would prevent some tragedies from happening in the Star Wars universe. For example, she might be able to save some Jedi who were killed during Order 66.

One challenge could be not being able to change things as easily as he thinks. Time might have its own rules. Another is that he might accidentally change something that has a much worse consequence later.

Well, he could potentially change a lot of things. Maybe he would prevent some of the tragedies that happened in the original timeline. For example, he might stop the Uchiha massacre. He could also use his knowledge of future events and the power of the Juubi to make the ninja world a more peaceful place from the start.

Well, in such a fanfiction, the characters might try to change past events. For example, Naruto could prevent some of the early tragedies in his village. Maybe he'd stop the Nine - Tails attack by somehow convincing his father not to sacrifice himself. This would change the whole future of the village and the relationships between characters.

She might change the course of events in the past. For example, she could prevent some tragedies that happened to her family. Maybe she would use her advanced knowledge to help her father, Tony Stark, earlier in his life, which could potentially lead to a different future for the Avengers and the whole world.

He might change the outcome of some crucial events. For example, he could prevent the Red Wedding from happening, saving his family and allies. This would completely rewrite the story's future, leading to a different power structure in Westeros.

He could end up altering the entire history of the Gem war. Steven might try to find a way to end the war peacefully much earlier. He could convince the Diamonds to change their ways before things got as bad as they did in the original timeline. This would mean that many Gems who were corrupted in the original story might not be corrupted at all. And the Earth would probably be a very different place, with a more harmonious relationship between the Gems and humans.

Well, he could change a lot of things. Maybe he'd prevent some of the big battles or save some characters who died. For example, he might stop Frieza from destroying Planet Vegeta earlier. It would be a whole new timeline with different outcomes.
